92 civic dx with d15b7 radiator fan issue
I recently replaced my thermostat because it was partly stuck open but another issue I am unsure of is a mix of 2 issues.
1. my radiator coming for the block is warm/hot and the one going to the thermostat is usually coldish, normal? also when running the heater my temp drops from normal to the bottom of the cold mark and will stay there regardless of weather
2. the radiator fan comes while parked and I let the car warm up, it comes on after maybe 7-10 minutes and stays on waited 5 mins and its still on but it does shut off when car is off. so my question is what is the normal fan operation?

Re: 92 civic dx with d15b7 radiator fan issue
i will do it again. but the car does not overheat and i drive from Tacoma to seattle 5 days a week. i was just wondering why the car is usually on the cold side. I noticed a drop in mpg and i read about the car not being up to temperature could drop mpg

i bleed it again. still the same. heater core hoses warm, return hose from block warm, hose to thermos housing cold. when i squeeze the hose the coolant would move, so i assume theres not a block?

but the radiator fan never goes off it just stays on after a certain temp and never goes off while parked, and with the heater on max and blower on the temp drops to cold mark and never recovers but the heater blows hot

Re: 92 civic dx with d15b7 radiator fan issue
my driveway is at a slope. I parked it with the frond end pointing up, I then open radiator cap and open the bleeder. Than i pour coolant into the radiator until coolant comes with no bubles. i refill coolant till full put cap on till first turn run the car till it warms up and did this three times.

Did you buy an OEM thermostat from Honda?

no i bought it from o reilys, but it was cold bottom hose and hot top hose before i changed it to. so if u leave the cap off and squeeze the hose the coolant moves. also when the cap is off and you rev the car up coolant comes out of the top, normal?

Re: 92 civic dx with d15b7 radiator fan issue
it doesn't cycle, it comes after temp is reached and stays on till the the car is shut off. but I found out when I tightended the thermostat bolt down it snapped. I got it out but I need to the junk yard to replace

Do you have a laser thermometer? If you don't, go buy one - they're like, $10 or $15 at Sears. Start the car, and point the thermometer at the radiator hose nearest the thermostat housing. Record the temperature when the fan kicks on, and then record how low it goes after 2, 5, and 10 minutes of running. Tell us those numbers. When was your thermostat last replaced, and was it replaced with a new OEM unit, or a parts store thing?
